Explanation:

To understand this, we will convert all given temperatures to Kelvin.
1°C = 274.15 K
The temperature in K = Given temperature in °C + 273.15
Here, we are given temperature in °C as 1.
So, the temperature in K is
1 + 273.15 = 274.15 K
1°F = 256 K
This is because, temperature in K = Given temperature in °F + 459.67
Here, the given temperature in °F= 1
So, temperature in K= =256K
So, 1°C > 1°F > 1 K
So, 1 Kelvin is the smallest temperature.

Hence option 2 is the correct answer.
